96.2% of my body weight comes from "organic elements" present in many

different forms. DNA, RNA proteins, lipids and sugars are all composed of

primarily O, C, H and N. Also, Water (H2O) and carbon

dioxide (CO2)as well as other small molecules involve these elements.

Oxygen (65.0%)

Carbon (18.5%)

Hydogen (9.5%)

Nitrogen (3.2%)

3.9% of my body weight comes from elements present in the form of salts.

Calcium (1.5%)

Phosphorus (1.0%)

Potassium (0.4%)

Sulfur (0.3%)

Sodium (0.2%

Chlorine (0.2%)

Magnesium (0.1%)

Iodine (0.1%)

Iron (0.1%)

The trace elements compose less than 0.5% of total body weight but then

again, they are essential for homeostasis. Some of these elements are

cofactors of critical enzymes in the body.
